Abbey Clancy and Peter Crouch are expecting their third child together.
The 31-year-old model and the 36-year-old football player - who already have daughters Sophia, six, and Liberty, two - are reportedly set to extend their family.
A source told The Sun: "Abbey and Peter are over the moon.
"Abbey has been quite open about wanting a third child - so they're happy another is coming along so quickly after Sophia and Liberty."
'Britain's Next Top Model' head judge Abbey previously admitted she was desperate to have more children but needed to convince her husband.
She said: "I'd love more, but the second one doesn't sleep at all - she's up every hour so Pete's like 'no more babies just yet'.'
And the star has also revealed that becoming a mother had made her a harsher judge on 'Britain's Next Top Model'.
She told BANG Showbiz: "I think I'm stricter from being a mum and I don't take any messing from my two [children] - especially Sophia, she can be a bit, she knows how to work us and she just gets away with anything with her dad.
"So I'm trying to be quite strict on the show. For me I just wanted the models to take it seriously and it's not like everyone is a model now with the likes of Instagram and everything.
"I wanted them to know it's not a walk in the park. It's hard work, it takes dedication you've got to be healthy, on it, and I just wanted them to listen because we have so many amazing photographers and designers that the girls are working with. I wanted them just to take as much in as possible to set them off because it's a great platform and a head start into the industry."
